Rosa plant named ‘Seliron’

ABSTRACT

A new rose of the Hybrid Tea class, characterized by its continuous good production of dark red flowers having a very good presentation in bud as well as open flower, borne singly on upright long stems on a bush of medium height, and healthy foliage.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the Hybrid Tea class, which was originated by me by crossingthe unnamed seedling SR89.013 (not patented) (seed parent) with ‘BlackMagic’ (not patented) (pollen parent). The female parent (pink, hybridT, very productive) has passed its good characteristicof growth, butdiffers clearly from the present invention by color and flower shape.The male parent is a darker red then ‘Seliron’ with glossy foliage. Thiscrossing was carried out in a greenhouse in De Kwakel.

The primary objective of this breeding was to obtain a new Hybrid-T typerose with a good presentation and budshape in different colors. Amongthe novel characteristics possessed by the new variety which distinguishit from its parents and all other varieties of which I am aware are:

1) A very large flower and flowerbud.

2) The warm red color of the flower.

3) Rapid growth of the plant.

4) Long flower stems.

5) Suitability for growing in many different areas.

Asexual reproduction of the new rose variety by cutting and graftingusing ‘Natal Briar’ (not patented) as rootstock, as performed in agreenhouse in De Kwakel, The Netherlands, shows that the aforementionedcharacteristics and distinctions come true to form and are establishedand transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING

The new variety of rose plant is illustrated by the accompanyingphotographic illustration, which shows typical specimens of the flowersof the new variety in different stages of development and as depicted incolor as nearly true as is reasonably possible to attain inillustrations of this type.

BOTANICAL DESCRIPTION OF THE PLANT

Botanical: Rosa L. cv. ‘Seliron’.

The following is a detailed description of this new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.). The terminology used in the color description hereinrefers to plate numbers in the aforementioned color chart e.g “55C” isplate “55C” of The Royal Horticultural Society Colour Chart.

Observations are made from specimens grown in a greenhouse in De Kwakel,The Netherlands, on a one year old plant. The color values weredetermined at 9:00 am on Nov. 26, 2002 under artificial light at DeKwakel. The following traits have been repeatedly observed and aredetermined to be basic characteristics of ‘Seliron’, which incombination distinguish this Rosa as a new and distinct cultivar.
